Frequently asked questions
All modules must be installed by licensed electricians in accordance with the applicable electrical codes. Protective clothing (non-slip gloves, clothes, etc.) must be worn during installation to prevent direct contact with 30 VDC or greater. Remove all metallic jewelry to prevent accidental exposure to live circuits. Take appropriate safety measures when installing or handling modules in light rain, morning dew or strong wind. Do not allow children and unauthorized persons near the installation site.
Each module must be securely fastened at a minimum of 4 points on two opposite sides. Canadian Solar Inc. recommends mounting rails with a minimum width of 60 mm. Install and tighten the module clamps to the mounting rails using the torque stated by the mounting hardware manufacturer. Use appropriate corrosion-proof fastening materials. All mounting hardware (bolts, spring washers, flat washers, nuts) should be made with stainless steel.
Regular maintenance is required to keep modules clear of snow, bird droppings, seeds, pollen, leaves, branches, dirt spots, and dust. Modules with sufficient tilt (at least 15°), generally do not require cleaning (rain will have a self-cleaning effect). If the module has become soiled, it shall be washed with water and a non-abrasive cleaning implement (sponge) during the cool part of the day. Do not scrape or rub dry dirt away, as this may cause micro scratches. Snow should be removed using a soft brush.
